Loading & Feeding Wire—MIG
Note: Always turn power off when working inside
the welder enclosure.
Note: It is a good idea to take the contact tip off of
the gun prior to feeding the wire.
8” or 12” Diameter Spool
1. Remove the plastic tensioning cover (1), load
spool with wire coming from under the spool (for
8” spool put spool spacer on first). Replace plastic
tensioning cover (tighten enough so the spool does
not turn freely).
2. Flip down the wire tensioning arm (2) and flip up
the left and right idle arms (5). Make sure the
grove size on the drive roll (5) is in the feeding
position that matches the wire size being used.
3. Feed the wire through the input wire guide (3),
across the left side wire guide roller, through the
center wire guide, over the right side wire guide
roller and in to the output wire guide.
Note: In order to prevent the spool from un-
winding; it is important to keep tension on the wire
until after the idle arm and tension arm are back in
place.
4. Flip down the left and right idle arms and flip up
the wire tensioning arm.
5. Turn the welder on, press the Quick Feed Button
to advance the wire quickly through the gun hose.
Note: If feeding problem occur because the wire
is excessively flattened, turn the wing nut on the
spring loaded tension arm (1) counter clockwise to
reduce the pressure. If the drive roll (5) is slipping
while feeding the wire; turn the wing nut clock-
wise to create more tension on the wire.

Adjusting Friction Break
While turning the spool with one hand begin tight-
ening the plastic tensioning cover with the other.
Once you start to feel tension; then turn the cover
an additional 1/4 to 1/2 turn.
The intent is for the friction break to produce just
enough friction to prevent the spool from continu-
ing to turn after the drive motor has stopped.

Warning
When feeding the wire, the drive roll, the connector
block and gun contact tip are electrically charged
relative to work and ground and remain charged
for several seconds after the gun trigger is released.
